Custom made parts for an FMC are RARE! lol. Harry D has some interesting info on the guy/manufacturer that made a lot of the aftermarket aluminum parts for the FMC's, even these ones for sale. I have a set on my rig, I would remove them but my factory side grills were highly modified (aka cut up) in order to fully suck in all the air from these custom aluminum side air scoops!! I've read threads discussing their was no engine temp differences when using these vs not. After reading the temp experiments with them in the past, I wanted to remove mine due to liking the factory side grill look.
